Anti-affinity rules are used to ensure that virtual machines are not running on the same physical host. This can be useful in situations where the administrator wants to ensure that virtual machines are running on different hosts for high availability and to minimize the impact of a host failure. By creating an anti-affinity rule via CLI, the administrator can ensure that the SQL Server VMs are running on different hosts while still leveraging high availability in case of host failure.
